As time had gone by, I have been made smaller and smaller.

I have been used in offices and homes since the 1970s.

Over time my memory has developed so much that, like an elephant, I never forget anything I have been told! Since the 1970s many new applications have been found for me.

I have also been put into robots and used to make mobile phones as well as help with medical operations.

I have even been put into space rockets and sent to explore the Moon and Mars.

Step I Revision Ask several students to retell the development of computer Step II Discovering useful words and expressions Ex 1.These are the meanings of some words or expressions in the text . Find out these words or expressions.

Check the answers.

Ex 2. Check the words meanings in the dictionaries. Then complete the passage with the words.

Check the answers.

Ex 3. Look at the phrases in bold in the story. What do they have in common?

They are all time phrases except “as a result”. They are used in the passage to indicate the development of the story. From them, we get a clear timeline of the story.

Step III Discovering useful structures

Let students find sentences in the present perfect passive voice in the text and then analyze their form and function. (activity 1 on page 21.) Students may find the following sentences: 1. I have been used in offices and homes since the 1970s.

2. Over time my memory has developed so much that, like an elephant, I never forget anything I have been told! 3. Since the 1970s many new applications have been found for me.

4. I have also been put into robots and used to make mobile phones as well as help with medical operations.

5. I have even been put into space rockets and sent to explore the Moon and Mars.

Then let students study these sentences carefully and sum up the form of present

perfect passive voice tense. Elicit the structure:

S + have/has + been + V-ed

1)

Why is the passive voice used here? When do we usually use passive voice? The passive voice is used when the subject of a sentence is the person or thing affected by the action of the sentence. We particular use the passive voice when don’t know or aren’t bothered exactly who has done something.

2). Change the sentences into the present perfect passive voice. Pay attention to the use of has/have. When do we use has and when do we use have? 3) Now write passive sentences in Present Perfect according to the words given. Show the following on the screen. 1 the postcard / send __________________________ 2 the pencils / count ___________________________ 3 the door / close _____________________________ 4 the beds / make _____________________________ 5 the mail / write _____________________________ 6 the trees / plant _____________________________ 7 the money / spend ___________________________ 8 the room / book / not _________________________ 9 the rent / pay / not ___________________________ 10 the people / inform / not _______________________ Answers:

1 The postcard has been sent.

2 The pencils have been counted.

3 The door has been closed.

4 The beds have been made.

5 The mail has been written.

6 The trees have been planted.

7 The money has been spent.

8 The room has not been booked.

9 The rent has not been paid.

10 The people have not been informed.

2)

Read the poem. Underline the use of the present perfect passive voice. Then decide which things have been done well and which have been done badly.

After students finish, check their work.
